Locking-coupling.



M. N. ANDERSON. LOCKING COUPLING. APPLICATION FILED MAR. 29, 1916' Patented Jan. 22, 1918.

INVENTOH WITNESSES m BY @m oil uni/0m] it may; concern: e it lliliOWn that l. liilARK ci iz n of the United States,

' in the county of i Eitzite of Ii, nnesota, have invented 0 new and useful improvements in i Couplings/{of which the following is it spe flotation.

My invention relates to a locking and coupling device,

At the present time, the anti-skid cheiins it. in connection with :uitoinebile or other vehicle tires are usually fastened in place by means of hooks which are nnsstis'i ectoi'y since the hooks often become detached.

The present invention has been especially devised with a view to providing a simple inexpensive and eiiicient iecliing; end cou pling device to he used in lieu of the sci hooks so as to overcome the chic :tions dental to the use of the hooks, and espe cially so as to overcome danger of detechment of the hooks.

A Further object is to provide 5:. locking; device having :1 retainin hoe it, :1 loch hem her therefor, and a slidel'ile springpressed holt operable to permit and to prevent move ment of the lock member.

ll ith the above, and additional ohjec as will hereinafter imp-er, the inve tion les been embodied in one pretence form as illustrated in accompanying drnwings and described hereinafter,

in said drawings? Figure-l is a view illustrating "proved device in connection with regments of en sntislzid chain;

claim:

1. lccli'ng device having lee r members, one me being" movable relatively to the member, e pivot bolt associated with members and longitudinally siideblc 1 id cit iisvin a non-cylinc cornice; sand lilifl A head or abutment l9 ill) Q esa-see bers against relative movement and having being cylindrical in cross section and formanother portion cylindrical in cross section movable with the bolt into operative relation with the said members to permit relative movement therebetween, and resilient means to hold the bolt in its locked position.

2. A locking device having locking members, one member being movable relatively to the other member, a transverse pivot boit associated with said members and longitudinally slidable, said bolt having a head on each end, a cylindrical portion at one end, serving as a pivot for said members, and a polygonal portion at the opposite end to serve as a lock to prevent. relative movement of said members, and resilient means to normally maintain one of said portions into eooperating relation with the pivot openings of said members.

A lockingdevice having a lock member provided with a receiving opening, a second lock member pivoted to and movable relatively to said first lock member and having a portion to close the mouth ofsaid receiving opening, sides depending from said portion and having each an opening registering with said receiving opening, a bolt forming a lock pivot for said members slidable longitudinally through polygonal pivot holes in said lock members, one end of said bolt fitting said openings to prevent relative movement of said members, the other end of said bolt gage over the edge mg a pivot of said members, a head on each end of said bolt, and a spring surrounding the bolt between one adjacent lock member.

4. A locking device comprising a lock member having a transverse opening for seeming an article thereto and a square opening for a pivot pin a'. second lock member of ll-shape in cross section adaptedto enoi the first lock member and having notches registering with its first named opening and also having similarly shaped pivot openings, a pivot pin passing through the pivot opening in both of said members and projecting beyond one side thereof, one portion of said pin being of similar shape to the pivot openings and adapted to prevent relative movement therebGtWCGIl, the other portion of th pin being cylindrical and serving as a pivot for the two members to operate, ahead on each end of said pin, and a spring surrounding the pin between one of said heads and theadjacent side of the locking device.
